Tests: guarded session ticket tests for old OpenSSL versions.
Much like SNI support, TLS session tickets are available starting with
OpenSSL 0.9.8f if TLS extensions support is explicitly configured, and
enabled by default since 0.9.8j. As such, SNI availability is checked
to ensure TLS extensions support is compiled in.
Additionally, the ssl_session_ticket_key.t tests for automatic ticket key
rotation, which uses session ticket key callback, as introduced in
OpenSSL 0.9.8h.
